Patent number: 11929115Abstract: A memory device and an operation method thereof are provided. The memory device includes memory cells, each having a static random access memory (SRAM) cell and a non-volatile memory cell. The SRAM cell is configured to store complementary data at first and second storage nodes. The non-volatile memory cell is configured to replicate and retain the complementary data before the SRAM cell loses power supply, and to rewrite the replicated data to the first and second storage nodes of the SRAM cell after the power supply of the SRAM cell is restored.Type: GrantFiled: April 8, 2022Date of Patent: March 12, 2024Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Jer-Fu Wang, Hung-Li Chiang, Yi-Tse Hung, Tzu-Chiang Chen, Meng-Fan Chang

Patent number: 11841586Abstract: A liquid crystal display has position-adjustable light sources. The light sources may be lamps, LEDs, or other emissive components. The light sources, however, are movable to adjust the locations or positions of their light outputs. The light sources ride upon electromagnet carriers. When currents are applied to the electromagnet carriers, each electromagnet carrier creates a corresponding magnetic field. The magnetic fields cause neighboring electromagnet carriers to attract or to repel, depending on the magnitude/polarity of the currents. The lateral and vertical positions of the electromagnet carriers may thus be adjusted by varying their respective currents and magnetic fields. Because the light sources ride on the electromagnet carriers, the light sources may be moved to refine an image generated by the liquid crystal display. The light sources, for example, may be moved to improve white/black contracts to reduce halo-effects.Type: GrantFiled: July 21, 2022Date of Patent: December 12, 2023Assignee: Dell Products L.P.Inventors: Ching-Feng Chen, Chao-Kai Huang, Yi-Fan Wang, Meng-Feng Hung, Wei-Ching Hsu

Patent number: 11797367Abstract: In some examples, a computing device may include a plurality of components, an embedded controller, and a read-only memory (ROM) to store a basic input output system (BIOS). A display device connected to the computing device may include a display panel and a timing controller. The embedded controller may be configured with instructions to determine that a power-on has been initiated, determine that a particular component of the plurality of components of the computing device has an issue that prevents booting the BIOS, and send a message from the embedded controller to the timing controller. The message may instruct the timing controller to display, on the display panel and before the CPU begins execution, one or more error messages associated with the particular component that has the issue preventing booting the BIOS. In some cases, a logo may be displayed along with the one or more error messages.Type: GrantFiled: August 2, 2019Date of Patent: October 24, 2023Assignee: Dell Products L.P.Inventors: Geroncio Ong Tan, Yi Fan Wang, Hong-Ji Huang, Craig Lawrence Chaiken, Timothy Carlyle Shaw

Publication number: 20230245613Abstract: An information handling system includes a host processing system and a Liquid Crystal Display device. The host processing system includes a graphics processing unit (GPU) and the LCD device includes a memory device and a DisplayPort Configuration Data (DPCD) register. The host processing system 1) determines whether the first GPU supports a Dynamic Display Shifting (DDS) mode, 2) when the GPU does not support the DDS mode, provides a first indication to the LCD device that the GPU does not support the DDS mode, and 3) when the GPU supports the DDS mode, provides a second indication to the LCD device that the GPU supports the DDS mode. The LCD device retrieves a Panel Self Refresh (PSR) setting from the memory device and stores the PSR setting to the DPCD register in response to the first indication, and retrieves a DDS setting from the memory and stores the DDS setting to the DPCD register in response to the second indication.Type: ApplicationFiled: January 31, 2022Publication date: August 3, 2023Inventors: Chun-Yi Chang, Yi-Fan Wang, Meng-Feng Hung, No-Hua Chuang, Yu Sheng Chang
